Product description
As an open IP20 unit with forced cooling, the Mitsubishi Electric MR-J4-350B4-RJ is installed in a control cabinet with an ambient temperature within the documented operating range of 0 to 55 °C. The full identifier assigns this single-axis digital AC servo amplifier to the MELSERVO-J4 range and its 400-V class. Rated motor power is 3.5 kW, distinguishing this power size within the series. On the mains side, this version requires a three-phase supply of 380 to 480 V AC at 50/60 Hz; the permitted range is 323 to 528 V AC. Rated input current is 7.9 A. On the motor side, the amplifier delivers three-phase 323 V AC with a rated output current of 8.6 A. The power stage uses sine-wave PWM and current control. SSCNET III/H provides communication with the higher-level controller. The interface side also requires 24 V DC with a tolerance of ±10 percent and 0.3 A. A dynamic brake is integrated into the unit. These characteristics distinguish communication, control and power supplies from one another without transferring values from other MR-J4 versions to this specific variant. The housing is 105 mm wide, 250 mm high and 200 mm deep; the net weight specified for the exact variant is 3.6 kg. For the specific order, these mechanical details are also taken into account when arranging shipping from Germany to the United States and other international destinations. External dimensions, mass, the 400-V class and the complete RJ model identifier therefore remain jointly relevant to installation planning and inventory comparison. The single-axis construction, SSCNET III/H and the stated input and output values together form the technical documentation for this variant. Product range, type number and suffixes remain a combined identity reference within that documentation.
The item supplied will have the stated manufacturer or type number and the stated condition category. Serial number, manufacturing date, labels, colour, packaging and normal signs of use or storage may differ. Specifications
